Tobacco roasting process of intensive hothouse

Abstract

The invention discloses a tobacco curing method for intensive flue-curing barns, which comprises curing step of three stages: a yellowing stage, a leaf drying stage and a stem drying stage. The difference between the method and the conventional curing method is that a second dry bulb thermometer is arranged in a tobacco loading layer for detecting the tissue temperature of tobacco leaves besides a dry bulb thermometer and a wet bulb thermometer arranged in the curing room. Fully considering the problem of heat generated by breathing of wet tobacco tissue, the tobacco curing method can controlthe temperature and the humidity in the flue-curing barn as well as the tissue temperature of the tobacco leaves. Specifically, the temperature of the wet tobacco tissue in the yellowing stage must be controlled within a change range of physiological and biochemical temperature of the wet tobacco leaves, which is the key for preventing the tobacco leaves from curing bad, thus ensuring the curing quality of intensive flue-curing barns.

Description

technical field [0001] The invention relates to a method for curing tobacco leaves, in particular to a method for curing tobacco leaves in a dense barn. Background technique [0002] In the prior art, the tobacco curing room includes ordinary curing room and intensive curing room. The difference between ordinary curing room and intensive curing room is mainly the difference in the amount of smoke, and the intensive curing room is 3-3 times the amount of smoke in ordinary curing room 6 times. Intensive barn is a more advanced tobacco barn that has been popularized and applied in recent years. At present, whether it is an ordinary curing barn or an intensive curing barn, most of the curing methods used are the three-stage curing process promoted by the State Tobacco Monopoly Administration, that is, it sets a dry bulb thermometer and a wet bulb thermometer in the barn. The bulb thermometer (generally these two thermometers are made into one, often called dry and wet bulb the...

Problems solved by technology

[0005] The main problem of the above-mentioned three-stage baking method is that it is only suitable for ordinary barns, but not for intensive barns. The main reason is that the three-stage roasting method is designed for ordinary barns. Due to the low density of smoke in the curing barn, it is basically unnecessary to consider the influence of the heat release of wet tobacco leaves on the curing process, while the density of smoke in dense barns is high, and the heat release of wet tobacco leaves is relatively large, which will affect the curing process. greater impact

The existing three-stage curing method ignores the problem of the temperature of the wet tobacco leaves, making it difficult to control the quality of the three-stage curing method when it is used in dense curing rooms. The tobacco leaves in the entire room are often burned. loss of tobacco leaves
